Title: Dc offset adjusting circuit and method
Inventor: IGUCHI HIROYUKI
IPC: H04L27/38
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To realize highly stable receiving sensitivity and adjacent channel selectivity characteristic from just after supplying power. SOLUTION: Through a prescribed period just after supplying power, the attenuation factor or the amplitude of a gain adjusting circuit such as a PIN attenuator 40, an AGC amplifier 42 provided on a stage precedent to an orthogonal detector 24 is controlled to generate a state of not-inputting to the detector 24. Input to a demodulator 26 during continuing the not-inputting state is averaged to decide a DC offset adjusting quantity in the demodulator 26. Since the influence of the converging situation of AFC (automatic control of a local oscillation frequency) and AGC (automatic control of the gain of the amplifier) of the variation pattern of a received signal is not received, the highly stable receiving sensitivity and the adjacent channel selectivity characteristic can be realized. It is also possible to reduce a time required for deciding the DC offset adjusting quantity.

Title: Method and device for measuring thickness of transparent film
Inventor: KASHIMA MASARU
IPC: G01B11/06
Filed: 1980-02-06
Abstract: PURPOSE:To make it possible to measure the thickness of a thin film in running with high precision by measuring the spectrum of transmitted light obtained by irradiating a transparent film with a parallel white light beam. CONSTITUTION:Through lens 2, light from white light source 1 is made into a parallel light beam and after it is transmitted in transparent film 3, the luminous flux has the width widened via lens systems 4 and 5 and is passed through the prism (or diffraction grating 6) to measure the spectrum through lens 7 and photodetector 8. Since the wavelength of interference light due to film 3 can be found from the maximum or minimum position of the spectrum, the thickness of the film can accurately be calculated. The parallel luminous flux is divided by half-mirror 12 and then separated by the prism (or diffraction grating) 9 into spectral component, and the spectrum of the light source is measured by prism 10 and photodetector 11 to monitor the fluctuations of the light source. Thus, the thickness of a thin film in running can be measured with precision.
